81
Q

Polar vs. nonpolar molecules

82
Q

What are minerals essential for?

A

Cellular Processes

83
Q

cholesteral

A

Cholesterol and triglycerides are important fats (lipids) in the blood. Cholesterol is an essential component of cell membranes, brain and nerve cells, and bile, which helps the body absorb fats and fat-soluble vitamins.

84
Q

Phospholipid bilayer

A

The bilayer creates a ‘sandwich’ style arrangement, where the hydrophilic heads of each layer face the watery environment inside and outside of the cell. This means that the hydrophobic tails are confined to the middle, creating a hydrophobic region between the two layers of heads. This allows for the plasma membrane to be stable in this dual watery environment.

85

Calcium

A

builds strong bones and teeth, clotting blood

86
Q

Magnesium

A

skeletal strength, normal nerve and muscle function, supports a healthy immune system

strengthens heart; is associated with a risk of high blood pressure, heart disease, stroke, arthritis, cancer, digestive disorders

88
Q

hypertonic

A

when substances come out of cells

89
Q

hypotonic

A

when substance go into cells
